Methods of treating a depressive disorder or an anxiety disorder in a subject in need of such treatment are described. A therapeutically effective amount of a composition comprising Ac-Nle4-c[Asp5-His6-(NMe)D-Nal(2′)7-Arg8-Trp9-(NMe)Lys10]-NH2 (PEPTIDE 9), in a pharmaceutically acceptable carrier is administered to the subject. PEPTIDE 9 is a selective MC5R antagonist, in which administration thereof to the subject can treat the depressive or generalized anxiety disorder with clinical improvement observed in a relatively short time.
摘要:
The subject invention pertains to a modified MC1R peptide ligand comprising a peptide that is a melanocortin 1 receptor (MC1R) ligand and a functionality or linker, such as a click functionality, for conjugation to a surface or agent. The modified MC1R peptide ligand can be coupled, e.g., via a click reaction with a complementary click functionality attached, to a moiety to form an MC1R-targeted agent. Drugs, contrast agents, polymers, particles, micelles, surfaces of larger structures, or other moieties can be targeted to the MC1R. The subject invention also pertains to a MC1R peptide ligand-micelle complex comprising a peptide that is a melanocortin 1 receptor ligand connected via a click reaction product to a micelle. The micelle is stable in vivo and can target melanoma tumor cells by association of the peptide ligand with the MC1R or the tumor and selectively provide a detectable and/or therapeutic agent (such as an imageable contrast agent and/or anti-cancer agent) selectively to the tumor cell.
摘要:
Melanocortin receptor-specific linear peptides of the formula Z-Xaa1-Xaa2-Xaa3-Xaa4-Xaa5-Xaa6-Y (VI) or a pharmaceutically acceptable salt thereof, where Z, Y, Xaa1, Xaa2, Xaa3, Xaa4, Xaa5, and Xaa6 are as defined in the specification, compositions and formulations including peptides of the foregoing formula or salts thereof, and pharmaceutical compositions for preventing, ameliorating or treating melanocortin-1 receptor-mediated or responsive diseases, indications, conditions and syndromes.
摘要:
Methods of treating a central nervous system (CNS) disorder or mood disorder in a subject in need of such treatment are described. A therapeutically effective amount of a composition comprising a melanocortin 5 receptor (MC5R) peptide ligand in a pharmaceutically acceptable carrier is administered to the subject. The MC5R peptide ligand is a selective MC5R antagonist, in which administration thereof to the subject can treat the CNS disorder or mood disorder with clinical improvement observed in a relatively short time.
摘要:
The present invention is directed to novel non-invasive diagnostic tools/compounds to image cancers, especially, melanoma, including metastatic melanoma in vivo. The present compounds exhibit enhanced uptake in cancerous cells and tissue and decreased renal uptake in kidney, evidencing favorable pharmacokinetics of compounds of the present invention. The compounds according to the present invention represent an advance in the diagnosis and treatment of melanoma, including metastatic melanoma using non-invasive molecular imaging techniques. The novel probes of the present invention are also useful for initiating therapy for melanoma as well as monitor patients' response to chemotherapy treatments and other interventions or therapies used in the treatment of melanoma/metastatic melanoma. Compounds according to the present invention may be used as diagnostic tools for a number of conditions and diseases states as well as therapeutic agents for treating such conditions and disease states.
摘要:
The present invention provides novel peptidomimetic macrocycles and methods for their preparation and use, as well as amino acid analogs and macrocycle-forming linkers, and kits useful in their production.
摘要:
The present invention relates to improvements in compositions containing peptides that are ligands of one or more of the melanocortin receptors (MC-R), or pharmaceutically acceptable salts thereof, methods for preparing such compositions, and method of using such compositions to treat mammals. In particular, the present invention relates to a pharmaceutical composition comprising a pamoate salt of Ac-Arg-cyclo(Cys-D-Ala-His-D-Phe-Arg-Trp-Cys)-NH2 which is a ligand of the melanocortin receptor subtype 4 (MC4-R), and in which, after subcutaneous or intramuscular administration to a subject, the peptide forms a depot at physiological pH that is slowly dissolved and released into the body fluid and bloodstream. The present invention may further comprise an organic component such as dimethylacetamide (DMA) or polyethylene glycol (PEG) with an average molecular weight of lower than 1000.
摘要:
The invention is directed to a pharmacologically active peptide conjugate having a reduced tendency towards enzymatic cleavage comprising a pharmacologically active peptide sequence (X) and a stabilising peptide sequence (Z) of 4-20 amino acid residues covalently bound to X.
摘要:
Linear peptides with a C-terminus —OH group that are specific for one or more melanocortin receptors, and which may be used in the treatment of melanocortin receptor-mediated disorders, including a variety of body weight disorders including cachexia, and for treatment of inflammation, immune disorders and other conditions, diseases and syndromes, and pharmaceutical compositions including such linear peptides.
